I realize this was a wink, but it is a valid problem with the "dot"-proposal.

Actually, it isn't. :) See below.

def foo(n): def bar(n): def baz(): return .n

So, which 'n' outer 'n' is being referenced?

Notice that this is a made-up example. Existing Python scoping rules don't allow this! Thus your example is not a bug, it's a feature request. And I say we say "no" to adding this feature. ;-)
